Newly discovered gene variant in Peruvian populations is powerfully linked with height. Five percent of Peruvians carry the variant, which originates exclusively from Native American populations. The variant occurs on a gene that, when mutated, causes Marfan syndrome, a condition marked by connective tissue abnormalities, including serious cardiovascular problems. The newly discovered variant is not associated with disease and may confer adaptive evolutionary advantage to populations that carry it.
